Disodium Zinc Pyrophosphate and Disodium (Europium) Zinc Pyrophosphate

Comparison of the isotypic solid-state structures of disodium zinc diphosphate (Na₂ZnP₂O₇) and disodium zinc diphosphate doped with europium (Na_1.94Eu_0.02ZnP₂O₇) shows the europium to share a sodium site and to exist at the intersection of two mirror planes in the layer-like structure. The emission characteristics of this rare earth containing material are reported.
